Why are you still recommending spergy shit like lang or landau to people who are new?

I'm not sure why it exists when it's completely superseded by Soviet books like N. Piskunov's calculus. It's strange to me that colleges choose instead to learn from a gay Canadian.

Soviets only know how to plagiarize

Ukraine is losing.

Because Stewart is fine if you're in business, but he only teaches through example really. You don't get a good generalized view of calculus

In the first statement it says "clearly b + |ab| belongs to S"

How TF did we get to this result?

Please help me you naggers I beg you

S is all positive `b - ak`

so k=0 and negative k

you can decide k yourself so pick k such `ak` = `-ab`

which is basically what the absolute sign signifies here

>so k=0 and negative k

(assuming b is positive)

so for the case `b - ac` where you pick c such that ac = `-ab` ...

I guess I should rephrase and say the absolute value is just to counter both the case where a might be positive and negative to make sure your multiple is in the right direction

I figured it out frens

>anon takes his first course in calculus

>they use stewart book

>anon fails hard

>have a second read with another textbook

>since this is the second time he reads a calculus book, things flow a bit better

>he feels like he's learning

>"so the problem was that Stewart was shit, huh"

No, you midwit, it's just that you studied calculus twice by now.

Is it generally good to learn calculus from Tom Apostol as first contact with the subject? I find it very difficult

It's pretty good if you're autistic, because he doesn't leave much unproven. What part are you having difficulty with?

Only the exercises, I don't have much trouble with understanding what's presented. For most of the exercises, it takes me too much time to complete them, or else I simply can't do them.

I am actually autistic though

I wouldn't worry then, because those exercises were written for an instructor or TA to give to students. Ideally, someone would be there to give you a well placed hint, and you'd probably figure out the rest. All of Apostol's answers are online so you could look up how to solve it, or ask here.

Also forgot to mention. Some of his exercises are just boring drill exercises, but an exercise is good if:

a) It tests to see if you really understood the material, and how can you ever know this until you're asked to recall it?

b) It focuses your mind to think hard about the subject matter.

Of course getting the right answer is important, but the next best thing is to use the question to see where you're going wrong.
